Weird topic title, i know. I recently bought Castlevania DS from gamestop, used. When I went to put in the cartridge, I noticed it was EXTREMELY sticky on the back. I don't know if some dumb fuckwad put a sticker on the back of the cartridge or what, but I got a new DS lite and I baby the hell out of it. So, i'm looking for something that could remove the stickyness. I could take it back, but it's hard to find so I would rather try to fix this. Also, it's a 30 minute drive one way.

To clarify, it is so sticky that if I press my thumb against the back, I can flail my arms and do jumping jacks and it does not budge. I got some of the stickyness off, but it's still a little more sticky than i'd like.
